I've Meanwhile, thenon-optional PvP element is basically just stealing the hard-earned resources of other players. he real goal of these games though is to get you to buy whatever points they're selling in order to speed things up. This goal results in gameplay that just isn't fun.

Don't get me wrong, they're totally addicting. That's the whole point. Each stage opens up a new thing that makes you a little bit more powerful so you keep thinking "now I can do This", but each stage of the game takes longer and longer and ultimately, nothing really changes. You're still do the same thing over and over again. It's addicting, but I get no joy in the experience. It's just hard to stop.

Meanwhile, thenon-optional PvP element is basically just stealing the hard-earned resources of other players. You log into the game to find another player has stolen resources it took you hours or even days to gather. Sure, you can attack them back, but them you lose the temporary protection obtained by having your base destroyed. And what's the point? Now they've lost time and resources.

This experience could be totally turned around by adding some additional strategy or RTS elements. As is, your attack units are completely mindless. After dropping them on the battlefield, you have no control over their behavior. They'll attack random (and strategically worthless) walls while being fired upon (and destroyed) by enemy units. Your defenses seem woefully underpowered (at least that's my experience) at repelling invading players. A single enemy unit was capable of taking down both shield generators and three turrets before being reinforced by the rest of the army for wiping out the rest of the base.

I have an SVG file that I'm using as the background image of elements on the page (using sprites). I wanted to dynamically update the color of the shapes and paths when theming the application, but I could not find a way to do this using CSS when the SVG is loaded as a background image (I have heard that inline <svg> elements will inherit style rules).

The way I solved the issue was to use a custom HttpHandler in my ASP.NET application that allows me to replace parts of the SVG with other content. Here's the code I used:

If you've upgraded to SQL Server 2012 and used the new Management Studio, you've probably noticed that your table and column names are now a teal color that looks exactly like the color of your comments. Previous versions of Management Studio would use the color specified for "Plain Text", but the new version uses a new setting.

To change the color, open the Tools menu and choose Options.... In the Environment settings click Fonts and Colors. Locate and click "Identifier" in the Display Items list box then change the Item foreground to something other than Default. That should do the trick.

In my last post, I mentioned how I had used Windows System Restore, only to find out that JavaScript (*.js) files are considered to be "system files" and are restored back to the state they existed when the restore point was created. I tried restoring back to the previous state, but no-go. System Restore failed with every other restore point.

I thought all was lost, until I found this article by the How-to Geek that has a batch file letting you mount the latest VSS (Volume Shadow Copy) volume and view the files contained there-in (when you create a Restore Point, Windows creates a VSS volume containing your files at that point in time). I didn't want the most recent volume, but I looked at the batch file and figured out how to list the available volumes and mount the one I wanted. I figured I'd document the steps in case this helps anyone else.

First off, you need to open a command prompt as an administrator (Right-click the "Command Prompt" and choose "Run as Administrator").

At the prompt, type

VSSAdmin List Shadows

This will list the available VSS volumes on your system. This can be confusing, but each one displays a creation time. What you're looking for is the the "Shadow Copy Volume" (e.g. \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1).

Once you find out the name of the shadow copy volumne, you can mount the volume using MKLINK just as you would any other folder (if you haven't used MKLINK, I'd recommend you check it out - it's a pretty useful tool). For example:

I discovered too late that Windows System Restore considers JavaScript (*.js) files to be system files. Apparently, the way System Restore works is it uses the Volume Shadow Copy service to back up your files, then during the restore process, it restores "system" files to their state at the time the restore point was created.

As a developer, this is bad for me, since I regularly create and edit JS files. After restoring my system, I opened up my code and found, to my surprise that all my JS changes had been reverted. If this happens to you, in my next post, I'll detail how I managed to restore the files.

I don't like typing document.getElementById (or document.createElement, etc.) repeatedly so for a while now, I've used my own function, I call byId (I know jQuery has $get, but I don't use jQuery, for reasons I won't go into here). This function started out as a simple:

function byId(id)
{
return document.getElementById(id);
}

In Internet Explorer, I could use var byId = document.getElementById, but this didn't work in other browsers. I then tried, what I though was a more elegant solution of binding byId to the document object (var byId = document.getElementById.bind(document)). This works, but it winds up being slower then then simple method in all browsers, but IE. I decided to publish my results on jsperf for anyone interested.

What's really maddening is that the best method is different in each browser. I'm sure any web developers have experienced this themselves.
